IBA's are key sites for conservation – small enough to be conserved in their entirety and often already part of a protected-area network. This series of publications gives details of each IBA in each region. The following regions are documented: Americas, Europe, Asia, Africa, Middle East and Caribbean. There is also a separate publication on the IBA's of Timor Leste. To view the Important Bird Area publications, click here To view all BirdLife's publications, click here
